Stewart S-51 Mustang Exact Scaled Down P51-D Nearly Complete
The Stewart S-51 is an all aluminum exact model of the North American P51-D Mustang at approximately 70% scale. The aircraft was designed by Jim Stewart over a period of about 20 years, and was offered as a kit in the late 1990s. It is normally powered by a big block Chevy V-8 engine in the range 454-573 cubic inch displacement. These engines normally make between 400-600 hp at 4750 rpm.
The design started out as a wooden aircraft powered by a small block Chevy V-8 engine. Eventually Jim started over with an all aluminum design, and for a while he sold plans sets. As far as I know only one or possibly two builders actually completed and flew a plans-built aircraft, and the first was in the metal fabrication business. Jim further refined the design and changed from a small block Chevy V-8 to a big block, and in the early 90's completed the plans for the current S51 kits. At the time it was the most accurate replica of the P51D available, and represented a quantum jump in complexity and performance over the slightly smaller SAL and FEW kits. In my opinion it's still the most accurate replica of a P-51D out there.
This is a 80% to 85% complete build and is currently disassembled and in crates ready to ship. It could be in the air in a few weeks. It is complete from the firewall back, and the engine has been hung. It still needs some wiring, cowling and air induction.
The engine is a Chevy Big Block 502 V-8 with a variable pitch constant speed 4 blade prop. Both engine and prop are 0 time.

Garmin GPS, Com 1, all engine instruments.
There is also a oxygen system on board.
